2-1. LOCATION
The Remote Hand Controls is equipped with a twenty
foot (6 m) interconnecting multi-conductor cord (unless
otherwise specified) which enables the Remote Hand
Control to be remotely located from the welding power
source or welding generator. The Remote Hand Control
can be wall mounted or placed on a stand at the work
area.
If it is necessary to install a muti-conductor cord of long-
er length, refer to Table 2-1 for cord conductor size ac-
cording to the desired length. Refer to Section 5 - Elec-
trical Diagrams for connections
2-2. INTERCONNECTIONS
1. To make connections on models equipped with
the twistlock plug, fully insert the twistlock plug
that is attached to the Remote Hand Control cord
into Remote Amperage or Voltage Control Re-
ceptacle on the welding power source or welding
generator. Turn the cap in a clockwise direction,
as far as it will turn, to lock the connection.
2. To make connections on models equipped with
the 14-pin or 5-pin Amphenol plug, align keyway,
insert plug, and rotate threaded collar fully clock-
wise.
